Multi-Spec Socket Engaging Structure With Corner-Wear Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional socket structures are limited in versatility as they can only accommodate metric specifications, failing to support British specifications or star-shaped screw members, thereby restricting their applicability.
Innovation Solution
The engaging structure features a mounting element with multiple first and second recessed portions and locking sides forming a hexagonal shape, allowing for the reception of screw members with metric, British, and star-shaped specifications, utilizing grooves and curved faces to prevent wear on angled corners and ribs during rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional socket structure with a single mounting portion is used, then the structure is simple, but it can only accommodate metric specifications and cannot support British specifications or star-shaped screw members
Solution Approach 1:
The mounting element is designed with multiple types of recessed portions (first recessed portions with grooves for metric specifications, second recessed portions with curved faces for British specifications, and third recessed portions for star-shaped screw members), allowing a single socket structure to accommodate multiple screw member specifications and types, thereby achieving multi-functionality and universality
Solution Approach 2:
The mounting element is segmented into multiple distinct recessed portions, each specialized for a specific screw member type. This segmentation allows each portion to be optimized for its specific function while collectively providing universal compatibility across different specifications
2Ease of manufacture
If the mounting portion has a simple structure, then it is easy to manufacture, but it causes wear on the corners of screw members during rotation
Solution Approach 1:
The second recessed portions are equipped with curved faces that match the angled corners of British specification screw members. This curvature design allows the corners to roll smoothly during rotation without concentrated stress, preventing wear while maintaining manufacturing feasibility through standard machining processes
3Adaptability or versatility
If the mounting element is designed for metric specifications only, then the design is straightforward, but it limits the hand tool to a single application
Solution Approach 1:
The mounting element integrates multiple recessed portion types within a single structure, enabling the hand tool to handle metric, British, and star-shaped screw members without requiring multiple specialized tools, thus achieving universality
Solution Approach 2:
Multiple specialized mounting features for different screw member types are merged into a single mounting element, combining the functions of what would traditionally require separate sockets or wrenches into one integrated component

AI summary
An engaging structure for a hand tool includes a main body. The main body has a mounting element. The mounting element includes multiple first recessed portions, multiple second recessed portions, and multiple locking sides. Each of the first recessed portions is provided with multiple grooves. Each of the first recessed portions is provided with at least three grooves. Each of the second recessed portions is provided with a first curved face. Each of the locking sides is arranged between two of the second recessed portions. Each of the first recessed portions is formed on one of the locking sides. The locking sides construct a first hexagon. The first hexagon has a center provided with a central axis. The first hexagon has six side faces. Each of the six side faces coincide with each of the locking sides.
